Climbing rose plant named &#39;Meivaleir&#39;

ABSTRACT

A new and distinct variety of rose plant is provided which abundantly forms attractive double blossoms having a luminous yellow-orange coloration. The plant exhibits a climbing growth habit, dense medium green semi-glossy foliage, and good vigor. The attractive medium green foliage contrasts nicely with the light-colored blossoms. The new variety is particularly well suited for growing as attractive ornamentation in the landscape such as in parks and gardens.

SUMMARY OF THE INVENTION

[0001] The new variety of Rosa hybrida Climbing rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the ‘Meipalsar’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the pollination of the ‘Korwest’ variety (non-patented in the United States) and the ‘Circus’ variety (U.S. Plant Pat. No. 2,074). The parentage of the new variety can be summarized as follows:

(‘Meipalsar’×(‘Korwest’×‘Circus’).

[0002] The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

[0003] It was found that the new variety of rose plant of the present invention possesses the following combination of characteristics:

[0004] (a) exhibits a climbing growth habit,

[0005] (b) abundantly forms attractive double blossoms having a luminous yellow-orange coloration,

[0006] (c) forms dense medium green semi-glossy foliage that contrasts well with the light-colored blossoms,

[0007] (d) exhibits good vigor, and

[0008] (e) is particularly well suited for growing as attractive ornamentation in the landscape.

[0009] The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens.

[0010] The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another.

[0011] The new variety has been named the ‘Meivaleir’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0012] The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two years of age and were observed during June while budded on Rosa froebelli understock and growing in outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

[0029] The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of two year-old plants during June while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France. The coloration in more common terms precedes reference to the chart in some instances. Such terminology is to be accorded its ordinary dictionary significance.
